LS6 camshaft
 

I'm looking for something a little better than the stock cam that's in my 5.3 motor. I'm thinking that an LS6 camshaft would give me a little better power range and make it sound better. I don't want anything to radical as I'm using the stock 5.3 truck intake/heads/computer. Of course I'm going to upgrade the valvesprings and do a little port work to the heads.

Any advice other than a ls6?

Thanks,
Nathan
